maintained therein which is to be retained at the water level line 7. The lower part-5 and extension 5"L are provided with a common bottom 8 which slopes from the outer end wall of the part 5 toward the end wall of the extension 5". This said end wall of the extension 5 is provided with a controlled drain 9 by means of which the water and sediment may be withdrawn from the reserve reservoir 6.

Suitably connected to the upper open end of the lower part 5 of the casing, as by the ianges 10, is the upper part 11 of the casing haing the reduced opening l2 in its upper en The reserve reservoir 6 and upper part 11 of the casing' are eachA provided with a re- 'movable man-hole cover v13 by means of whlch a person may gain ready access to the interior of these elements.

The upper part 11 of the casing has suitably bolted to its lower portion the substantially pyramid-shaped plate 14 which is shown in detailin Figs. 3 and 6 as comprising the four fiat sides 14a having the flanged upper edges 14h and the elongated openings 14 formed in the edge ortions vwhich vare bolted to the wallpof t e casing part 11.

The function of thispyramid-shaped plate 14 will be disclosed at a later oint.

Suitably housed within and olted to the upperA part 11 of this casing are the perforated centrally aperturedy plates 15, 16 and 17 which are of substantially identical construction, the only variation consisting 0f the diameter of the openings formed. in the centers thereof, the said openin increasing in diameter gradually fromt e late 15 to the plate 17. These plates are epicted in detail in Figs. 2 and 5 and are formed with the perforated fiat wall 18 having an upwardly turned ange 19 bordering the central opening'and a downwardly turned fiange 20 at the outer edge byfmeans of which they.

aredsecured to the walls A.of the upper part of the casing by the bolts 21. The specific function performed bythese plates will be disclosed indetail-'at a later point.

In Fig. 1, the upper, end pf the part 11 of the casingis, illustrated as having a baille struc-ture including the' vertically extending parallel lpla-tes 22 f-havin 'arranged in lthe v l y h -spacesbetween the same t e zigzag pl'ates 23 with the lower part A-5'..whatpwill be termeda u Thefunctionperformedgbyfthls balile struc- Ahaving thej-perforation's 24' formed' therein.

ture will be clearly disclosed atalate point. In Fig. 8 there is shown a modified form of baile structure which includes the transversely extending hollow element having its longitudinal edges arranged on horizontal and vertical planes at right angles to each other. x Surrounding the hollow structure 25 are the V-shaped baille plates 26 which are arrangedto form V-shaped passages 27 beitween the walls of the plate 26 and the hol- -low member 25. I This structure is supported v :by .a transversely extending bar 28 bolted to the'sides of the upper part 11.l

If desired, for particular usesto whichthe. apparatus may beput and which will be de' scribed at'a later point, the baille structures 4may be dispensed with and a transversely extending rod 29, journaled in the walls of the u per part l1 of the casing, maybe provide for supporting the hollow. damper lstructure 30 and vfor raising and '4 lowering the same in respect to the central openings formed in the perforated plates 15 to17 in# elusive for varying the amount of air which may pass through ythe upper part v1l oi the. casing and rout through its reduced upper end 12. This rod 29 has mounted 4thereon a roller 31 having the section of chain 3 2 con-A nected thereto and to the hollow 'damper 30.

A crank handle 33 is'rformed on one endof this rod 29 and provides means by which i* the rod 29 may be rotated for winding or o rates to retain the damper 30 in any de unwinding the section of chain 32 in respect to the roller 31. A pawl and ratchet structure 34 is also associated with this rod ,and

Suitably mounted upon the top wall ofthe extension 5a is a base plate 35 which has the electric motorr bolted thereto and the pump 37 directly connected with thel armature shaftof the said motor. The free end of the-pump shaft 37 has mounted thereon the fan 38 which is arranged in an opening formed in the wall of the lowerpart-5 of the casing and has surrounding it an annularwat'er shield 39 which projects into the. said art 5.0i the casing. It will now be seen t at when the motor 36 is operated,vthe

fan will be driven for orcin air into the casing which will pass upward y through the central openings in the plates 14-to117 inl escape through the reduced The pump 37 is provided with a feed pipe 40 which-extendsfinto the reserve reservoir 6-and has connected to its lower end a sucther provided' with a check valve 42 .which o crates to revent the flow-of liquidfrom will new lie-seen thatwhfen this punip is operated-'byv the motor| 36,'.4 waterv lwill be -sucked through the nozzle 4 1, by fthe'check valve42, and through the feed pipe `40 into a rat back into 'the reservoir 6.A It

the said pum The said pump is provided with a pipe line 43 having a control valve 44 interposed therein. This pipe line is provided with a union 45 by means of which it may beconnected to a pipe extending to a condenser of a refrigera'ting plant, .not shown. i This pipe 43 :is further provided with a coupling 46 by means of which the pressure gauge 47 the thermometer 48, the.

primer cup 49, and the drainvalve 50 may be connected thereto; These various instrumentalities may be used-in any desired manner for permitting the proper control and functioning of the pump 37 in connection with the refrigerator condenser.'

The return for the-water fed to the refrigerator condenser includes theip'ip'e 51:

which passes horizontally into the vlower -part 5l of thecasingand terminates in a sprayinglnozzle 52 which functions to break the stream 'of water upinto amist or spray. For the purpose of taking care of any evaporation in the amountiof water in the recooler and the condenser'portion of the .refrigerator system, a supply line 53 is provided whichleads from the city water sup- .condenser of a refrigerating plant, the motor 36 is started for the purpose of driving the pump 37. This pum will draw water from the reserve reservoir 6 and will feedA the saine to the condenserof the refrigerating plant. This water will absorb heat while passing through the refrigerator plant and when it is returned to the apparatus through thepipe 51 andV sprayed into the casingl by the sprayer 52, the said water is at er high temperature. The operating of' the e1ectricmotor36 and pump 37 will causethe fan 38 to be rapidly rotated for.-l

driving airinto the lower'part' of the casing. This air .can-only escape by passing .upwardly 'through the central openings 4of 'the plates-14m -17 inclusive and by the baffle structures to Athe lreduced openin 12 vof ,the upperpart "11of. the casing. j is upward draft will blow the'. spray of water thrown outbyfthe' `sprayer '52` upwardly .;through the central openi'ngs'of the plates 14 to 17 'after whi'g'ah'itnwil-lV impinge against f "the baffle vstructure in the-nippel*"portionof the casing 'zirtill ancLwilI becaused todron water will' substantially :completely ,joined claims.

checked by the perforated plates 15 to 17 which will split the water up into drops resembling rain. These rain drops will pass through the plates 17, 16 and 15 and will drop upon the sloping flat walls 14a of the pyramid-shaped plate 14. The said drops will then collect or unite and will be permitted to drain troni the plate 14 through its elongated openings 1 4". This water draining through the openings 14C will be deposited inthe reserve reservoir 6.

lt will readilyv be understood that the air forced into the casing by the fan 38 will be thoroughly mixed with .the water sprayed from the sprayer 5i). and the rain drops alling into the plates 15 to 17 inclusive and will absorb all of the heat carried by the said water during its upward and return travel so that when the water is deposited in the reserve. reservoir 6, it has been greatly reduced in temperature and is in readiness for `again being sucked into the pump 37 and fed to the condenser of a refrigerating system. If this apparatus 1s to be used for cooling and washing air, 1t 1s operated 1n the same manner as described and the air driven in-V to the 'casing by the fan 38 is collected as it leaves the upper reduced end 12 and conducted to any point desired. It is,'of course, to be understood that the water used in the system, when employed for cooling'air, will be the cooling medium and that the pipes 43 and 51 will be directly connected so that the water discharged from the pump 37 will be fed directly to the sprayer- 52.

The damper shown in Fig. 9 may be employed when the device is used for cooling or washing air for the purpose of controlling the amount of air permitted to be. discharged through the central portions of the plates 15 to l'inclusive.
